Application filed January 21, 1915. Serial No. 3,474.

To all whom it may concern Be it known that 1, JOHN H. BARR, c1t1 zen of the United States, and resident of the borough of Manhattan, city of New York, in the county 'ofNew York and State of New York, have invented certainnew and useful Improvements in Type-Writing Machines, of which the following is a spoon fication.

My present invention relates to ribbon mechanism for typewriting machines and lts general object is to provide improved mechanism of the character specified.

More specifically one objectof the inven tion is to provide new and improved means for varying the vibratory movement of the ribbon so that its different widthwise portions or color fields may be employed at will. Another object is to provide novel means for dispensing entirely with the use of the 10 Remington typewriting machine embodying the preferred form of my invention. parts of the machine being omitted and parts broken away. Fig. 2 is a fragmentary front elevation showing indicating devices and a finger piece and associate parts for controlling the ribbon mechanism. Fig. 3 is a transverse vertical sectional view taken one. plane indicated by the dotted line in Fig. 1 and looking forward. Fig. 4 is an enlarged vertical sectional view taken on a plane indicated by the dotted line y-y in Fig. 8 and looking in the direction of the arrow at said line. Fig. is an enlarged perspective view of the ribbon vibrating and controlling mechanism. Fig. 6 is a plan view partly in section of certain parts of the ribbon vibrating and controllingmechanism. Fig. 7 is a horizontal sectional view taken on a plane indicated by the dotted linee-2 in Fig. 3. s

As appears from Figs. 1 and 3 the main frame of the machine comprises a base 1, posts 2 and a top plate 3 which support fixed guide rails 4 on which runs a carriage truck A platen 6 is mounted in a platen ed to run on a shift rail 12 supported by upright arms 13 rising from a transverse bar 14 which is supported by upright arms 15, each arm 15 being pivoted at its lower end at 16 to a lever 17 provided with a shift key 18. The platen normally stands in its lower case position as shown in Fig. 1 but may be raised or shifted to upper case position by depressing either of the shift keys 18. The rail 12, cross bar 14 and-uprights 13 and 15 constitute a shifting frame for controlling the shifting movements of the platen to operate either of the shift keys 18. Printing key levers 19 are provided'with keys 20 and are connected by links 21 with sub-levers 22, said sub-levers in turn being connected by links 23 with frorit-strike type bars 24: mounted on hangers 25 secured to a stationary segmental support 26. A universal bar 2'7 underlies the key levers and is supported on arms 28 depending from crank arms 29 which project rearward from a transverse rock shaft 30 having end 'pivots supported in the sides of the base. Projecting from said rock shaft near its middle is an arm 81 which is connected by a link 32 with certain of the escapement devices (not shown) but which are of ordinary construction.

Ribbon spools 33 are supported one at each side of the machine below the top plate on shafts 34 and a ribbon 35 is wound on said spools and led upward therefrom through openings in the top plate, thence over stationary guides 36 and through. guide openings in the head or upper portion of a ribbon carrier or vibrator comprising a pair of parallel wire guide loops 37 rising from a body portion 38, said vibrator being arranged about centrally between said stationary guides.

The construction of this rod is best shown in Fig. 7 from which it appears filial die rod is pmda'on G and is reduced slightly in diameter at one side of the threaded portion. it ilis opposite end the rod has a nick 63 by which said rod may be screwed into the bracket 58, one car 60 whereof is formed with a threaded hole to coiperate with the threaded portion After the rod is threaded in place a locking nut 64- may be screwed on the portion until. it abuts the outer face of the ear 60, thus securing or looking the rod in fixed relationshipwith In the course of the assembling of the rod 61. on bracket the parts for which said rod provides a pivot are also assembled in place. These parts are best illustrated in Figs. 3 to 5 and i and comprise two acboaters or levers 65 and 66 which have a common pivot heingarranged to turn or i lizlcrum on the rod between the cars 60. 'lf'hc'lc'ver or memberfifi is provided near its lower end with a cross portion 67 which terminates in forwardly bent cars 68; while die lever 66 has a cross portion. 69 terminating in rearwardly bent cars 70. T ie two sets of cars are perforated so that the rod 61. may pass hhrough them." The cross portions 69 and 437 are of sucl'i length that the ears 70 are embraced loosely between the cars while chose latter ears are loosely confined between the cars 60 of the lnracket The lever '65 is constantly connected with the downwardly extending arm 50 of the operating hell crank by a link 71-, while the lever 66 is arm 50 by a link 72. the link 72 and at its ally connected as by a. shoulder screw 73 bent forward from the side at its upper end. The rear end of the link 71 is pivocally connected by a shoulder screw 75 with an. ear 76 bent reamrard from the arm 50 about midway of Thelink 721's pivotally conat its forward end by a shoulder he lever 56, said shoulder The link 71 is above screw being threaded into an car 78 bent forward from the lever somewhat below iis upper end. The rear end of the link 72 is pivotally connected by a shoulder screw 79 with an car 80 bent backward from the aid car 80 being ah the opposi'e side edge of said. arm from the car 76. The links 71 and 72 incline downward and rearw 73 and 77 so that gles to a horizontal line passing rhrough these pivots; Said pivots dur- ,z'ney be vertically adjusted.-

provided with a threaded f constantly connected to-the forward end is pivotaid from their respecmasses ing the platen shifting operation remain ing lever'which is supported from the platen shifting frame. that during the platen shifting operation The links are so' disposed they cross the horizontalor median lines and at the end of such operation are at the same angle to said lines but above them as normally they are below them. It will be observed that as the result of the platen loosely confined when it is desired to render them operative. The forward edge 91 of the lug 89 is adapted to operate as an actuating surface. The construction is such that by effecting a relative shifting movement between the frame 81 and the actuators 65 and 66 either actuator may be brought within the passage-way 90 and thereby rendered shifting operation the ribbon vibrator operby the shift.

ating lever and links are moved or shifted while the elements of the ribbon vibrating mechanism belowfsaid links are not affected It will be observed that the pair of links 71 and 72 are at all times or constantly connected to the parts linked together by the links, viz., the arm 50 and the respective levers or actuators 65 and 62, as distinguished from a construction like that of my prior Patent No. 1,016,927, granted Feb. 13, 1912, wherein a, pair of links are shown in combination with devices for at will making and breaking their connection with one of the two parts or elements which they link together. It will also be noted that the two key operated actuators or levers .65. and 66 are constantly connected independently of each other to the vibrator.

While the actuators 65 and 66 are both constantly connected with the -operating lever, means are provided for rendering them separately or alternately effective at will to operate said lever, said means comprising a rocking frame or actuating levels member designated as a whole by the refer i encenumeral 81. The frame 81 is rectangular in shape and comprises a sheet metal portion bent into a U-shape and inverted, providing a top 82 and parallel side portiens 83, the side portions being connected 92 is hired as by rivets 93 to the central arm i 31' on the rock shaft 30, said finger 92 being adapted to act against the rod 84 to swing the frame 81 'pivotally. about the rod 61 as a center and co-axially with the levers 65 and 66 whatever may be theposition of said frame endwise of said rod.

In the present instance the relative shift or resetting between the frame 81 and the two actuators is preferably effected by shift ing the frame endwise back-and forth on the rod 61, so as to select the actuator to be operatively vibrated. Thus to shift or variably move the frame 81 endwise, hand operated means are provided comprising as shown in Figs. 1, 2, 3 and 5 a link or arm 91 curved upward at its inner end and terminating 'in a forwardly bfent portion which engages loosely in a slot formed-in a lateral car 95 projecting outward from the lefthand side portion 83 behind the pivpt rod 61, so that vibratory movements of the"frame 81 will only slightly affect the link 94., The outer or left-hand end .of the link or bar 94 is pivotally connected at 96 with a crank at their lower ends by a cross rod 8 1. The

side portions are perforated and reinforced with bosses or hubs 85 to fit over and bear both rotatably and slidably on the rod 61, 62, outside of the ears 60, the frame 81 being thus mounted ce-axi ally with the actuators 65 and 66. The upper portion 82 of the frame is rectangular in shape, as best shown in Fig. 6. This rectangular part is cut out providing an opening or slot '86 near the right-hand side and a smaller opening 87 at the left-hand forward corner. Between these openings at the front side is a triangular lug 88 which approaches closely a lug or thickened portion 89 at the lefthand rea'r corner of the frame,'the space between the lugs 88 and 89 providing a narrow opening,'passage-way or throat 90 connecting the slots 86 and 87 and within which the upper portionsof the levers 65 and 66 arm 97 fixed to and projecting downward from the rear end portion of a'rock shaft 98 extending fore and aft of the machine at its left-hand side. Behind the crank arm the rock shaft bears in an angular bracket or arm 99 which is secured by screws 100 to.

the type bar segment 26. The forward end portion of the rock shaft bears in a plate 101 secured to the left-hand front post 2 by screws 102 (Fig. 2). In front of the post the rock shaft is provided with a. knurled button or finger piece 103. Behind the arm 99 the rock shaft has fixed to it an upstanding spring finger 104 having a head formed with holes 105 which are adapted to cooperate with a lug or projection 106 on the rear face of the arm 99 so as to hold the rock shaft 98 and connected parts including the frame 81 in adjusted or set positions. p

Indicating devices are preferably provided for facilitating the proper adjustment of the ribbon throw varying mechanism, said devices comprising suitable indicating marks or colors 107 on the front face of the plate 101, a pointer 108 fixed to the rock shaft 98 coiiperating with these indicatingmarks. The middle mark 107 corresponds to the upper field of the ribbon 35 which in beyond the present instance is preferably a lei-color ribbon, the upper stripe or field a being black and the lower stripe or field 2; being red. When the pointer 108 is opposite the middle.indicating marl: the shaft 98 will be blocked against further turning movement in clockwise direction by a stop 109 which is at this time in contact with the stop end 11-9 of 2i nien'iber 111 which is curved to partly surround the shaft 98 and is pivoted at .112 to the adjaccntcorner post A finger piece 113 is provided for conveniently swinging up the stop member 111 so as to lift the stop 110 out of the path of theistop 105) and permit further turning of the shaft 98- until the pointer 108 is brought opposite the top indicating mark .107 at which time the ribbon throw changing parts controlled by the button 103 will be adjusted so that they will be inactive at prin ing operations, or, otherwise expressed, will be in milliongraph. position as hereinafter plained. Thereafter during turning out the finger button in opposite or counter-clockwise direction the stop 109 willpass from under the stop end 110, permitting the stop member 111 to drop down by force of gram .ity until arrested by the engagement of the end portion 110 with a collar 11 1 which may be fixed to the rock shaft 98 behind the "plat The step .109 projects radially l t periphery this collar and its path is nornially intercepted by the stop end 110 so that turning movement of the shaft 98 to render the ribbon throwing devices inoperative is impossible unless the step 110 is lifted up out of the path of the In order positively to limit the exterts of throwing movement of the ribbon, stop devices are provided comprising, best shown in Figs. 4-, 5 and 6, a stop plate 115 which is arranged on top of the usual spacing plate 116 secured to the upper face of the type bar segment 26. The stopplate 115 is provided with a longitudinal slot 117 which receives a headed the plate is adjustably secured to its stationary support, viz the segnientiZG. The rear end of the plate 115 is turned down to provide a vertical stop face proper 115 which is always in the path of the forward edge of the part 82 of the vibratory member or frame 81 and always arrests said frame at the same point in its movement. The front end of the plate 115 is narrowed to provide a finger 115 which is just wide enough to pass between the upper or portions of two adjacent hanger washers secured in place as usual by screws 120 o the hangers 25. This arrangement prevents the plate 115 from showing. lVhen the screw 118 is loosened the only movement of which the plate is capable is a straight fore and aft I one. The screw and slot connection 118, 11?

of the stop plate with its support permits 0 I more rully exstop 109. dilt'erent screw 118 by which '98-, crank arin masses fine adjustment oi the stop plate when the parts are assembled but after such adjus'tment the stop plate is set rigidly on its sta-' tionary support by tightening the screw 118 a1. thereafter there is no variation in or adjustinont of the fixed or stationary stop which is inaintained in a single-uhvarying. position for the varying throws or vibratory mov ments of the ribbon carrier, as will be 1 "or understood from what follows.

Assiuning the parts areadjusted as" in Figs; 3 5 and .6, it will be understood that when a printing key is depressed the shalt 30 .wil be rocked as usual and will cause the Dr 92, acting the rod 84, to swing T nine 81 on its tulcrunr The upper por tion of the frame moving forward Will actuate the lever 66 whose up per end at this time is embraced within the passage-Way so that, the edge 91 will act to push said lever forward, the lever becoming in efleot a part of the frame 81, At this time the lever 65 will be in the opening" 86 and will be inactive although it will swing idly fora result of the inovementimparted to the operating lever through its connection the lever 66. As a result of this, movement of. the operating lever the vibrator will he lifted to interpose the printing portion of the ribbon in the path of the actuated type bar. The parts are so. proportioned adjusted that when the front edge of the part 82 strikes thestop 1.15; thus positively arresting the vibrator and connected train of actuating devices, the upper edge portion or held a of the ribbon will be presented opposite the printing point. This same extent of movement will be communicated at each. vibratory movement of the ribbon as long as the parts are maintained ad- 106 justed as described so'thattype' impressions will follow a straight path. longitudinal of and about central of the upper field a.

When it is desired to use the lower ribbon held 6 the finger button 103 is turned counacting through the rock shaft 97 and baror link 94 to slide 81 bodily rightward until its up per portion reaches the position. indicated by dotted lines 82 in F 6. The frame will be maintained in this new position as in the previous position by the detent devices 105, 106. Asa result of this adjustment the passage-way 90 will be caused to embrace the upper end of the lever 65 while the lever 66 1 0 ter-clockwise the frame will be located in the opening 87. Consequent vheu the iranie 81 is actuated .during printing operations the edge 91 acting against the lever 65 will operate the same and the niotior from said levers will be tr'ahsmit- ,12'5 ted tl'irough the link 71 to. the operating lever 49. .flt the start the edge 91 will he in contact with lever 66, but the motion of this lever his tinle will be so'rapid, owing to I the hat it is being pushed bytheann incense 50 which is being pulled by the link '71, that the lever 66 will move forward away from the edge 91. As before, the movement of the -parts will be arrested by the contact of the 5 edge of the part 82 with the stop 115 but- I crating lever than does'th e link 72. :The

parts are so proportioned and adjusted'that as a result of the longerthrow transmitted to' the vibrator the lower ribbon field b will be presented to the types. Both in this adjustment of the parts and in the prior described adjustment of the. ,parts they will be restored to normal position chiefly by gravity when the printing keys are released although the usual rock shaft spring (not :15 shown) will act on the rock shaft and finger 92 as well as on the universal bar to estore them. 4 g

When it is desiredto set the parts for mimeographing the stop member 111 is lift 30 ed as described and the finger piece 108 I turned until the pointer 108 is brought opposite the top indicatingmark 107. This movement of the rock shaft transmitted to the frame 81 through the described train of connections will cause said frame to be slid bodily leftward along its fulcrum rod 6L until it is brought to the position indicated by the dotted line82 in Fig. 6. As a result of this adjustment both levers 65 and 66 will be maintained simultaneously in the.

opening 86 so that at printing operations the frame 81 will be caused to swing idly on its pivot without affecting either lever 65 or 66, which levers, together with the ribbon e5 vibrator and operating lever, will remain motionless in normal position so that the types may strike against the paper or work" sheet on the platen without the ribbon being interposed in their paths. The adjustments may be such that the'normal position of the vibrator in mimeograph condition may be I somewhat lower than when the ribbon is being used.

Various changes may be made Without de- 56 parting from the spirit and scope of my invention. v
